Hi Georgia,
I found this page with Brokeloh listed with the Catholic Church in
Nienburg. There is an email address which you could use to make an inquiry:
http://www.kath-kirche-hannover.de/2,0.asp?id=54
The detailed atlas I have does not show a church in Brokeloh, but one
could guess that their church might be Husum which has records from 1774 on.
That comes from this page: http://www.hist.de/ynienburg.htm
I haven't found a church address for this one. This is the webpage for
the town of Husum:
http://www.meinestadt.de/husum-nienburg/home
Perhaps there is an address there to contact regarding the church.
Landesbergen is also near Brokeloh which shows a church on the map. Here
is a webpage for the Evang. Church there (with an email address):
http://www.evlka.de/extern/stolzenau-loccum/kk/gemeinden/landesbergen/kontak
t-landesbergen.htm
You may have to copy and paste this last address since it is so long.
I hope this helps!
Barbara
